More than 2 YAML front matter delimiters ... false positive in profileScoreDist

[vjcitn]

This event comes up with profileScoreDist but the vignette seems to compile OK.

* Checking formatting of DESCRIPTION, NAMESPACE, man pages, R source,
  and vignette source...
Error in .rmYAMLfm(lines) :

There are two things of interest here

• should we have a guideline to ensure this does not occur?
• the event crashes BiocCheck ... it does not finish when it runs into this. Should we have a try or other approach to fault tolerance?

should we have a guideline to ensure this does not occur?
I think this is a rare event and would not require guidelines IMO.

I am not familiar with reference system they are using. Is it possible to only use one set of ---?

I've converted the error to a warning and have made the code more robust to multiple instances of ---.
